Fix Missing Sequence in PO

This is #23 on the FXMENU maintenance utility for SCS use only and is not on a standard menu.

This utility can be used to re-sequence the line item detail in Purchase Orders when the sequence numbering is broken.
 This could occur when line items are deleted and the remaining records are not re-numbered correctly.

No audit record is written to the Audit Log for re-sequencing corrections.
